    Hello everyone,

    I just installed the Snow Leopard and run a quick Xbench in it, I am surprised my OpenGL score dropped more than a half in SL. I was wondering why is the cause to this?

    Is XBench 1.3 support SL at all? Or is it because of the new OpenCL language?

    Below is the result:

    Thanks for all your help!!:)

    P.S. Sorry for the formatting. I don't know how to make it not cramp together.

    Anyone has any ideas?:confused:

    Some more information to add:

    when I installed the SL, the screen went completely black and I originally thought the installation failed. However, it was actually a pretty common problem with some new 09 MBP that the graphic driver is somehow 'disabled'/'crashed' during installation. I completed the installation with aid of flash-light - and once it rebooted everything is normal.

    Could it be a graphic driver problem making the OpenGL score so low?
    Please, any comments is mostly welcomed!!;)

    It's normal and no one knows why...yet. For some reason, early benchmarks show that graphics/GPU performance is lower than Leopard. Head over to Engadget and look for their Snow Leopard review.

    Thanks for your comment.

    It is glad to know I was not just me making some wrong setting.:rolleyes:

    I hope they will fix this soon....it jsut doesn't make sense why SL will run slower in graphics than leopard.

    Could it be Xbench and not SL? Xbench is really old. Like over 3 years without an update kinda old.

    Glad I found this post... it was driving me nuts most of this afternoon. I had just installed SL on a 3rd drive.

    I have:

    drive1. Leo 10.5.5 = xBench @225

    drive2. Snow Leopard 10.6.2 = xBench @188

    drive3. Windows 7 = who cares :rolleyes:

    like most benchmarking tools, xbench is synthetic. we all know what that means right?? :rolleyes: ;) :p

    This.

    XBench was once good, but people need to get past this.

    In general, people should ignore all benchmarks (old or new) that show Apple products in bad light. :D

    How about some Geekbench scores then.

    Leo = 4909
    Snow = 5836
